Julio H Morimoto 1b680d3a54 Provide better defaults for ingress tls and secretName configuration. (#5859)
This patch allows tls to be enabled with an empty secretName for ingress controllers might be able to provide a default certificate.

Fixes #5858, provides better defaults for the Ingress object and allows TLS to be enabled with an empty secretName.

### Motivation

The current helm chart can create an Ingress with TLS, but it requires a secretName to be added. This is not an Ingress requirement and, in some cases, the ingress controller can provide a default certificate when the Ingress object does not declare one.

### Modifications

Modifications include `values.yaml` and `dashboard-ingress.yaml` to address the issue.
